Murphy & Kittinger Vianadi

03-09-2018, 03:49 PM

I was looking for a lower cost alternative to the
canTiLena Speaker for a three way--that SS revelator woofer is just over budget. I stumbled upon the Vianadi. I see no reference to this design anywhere else. The driver selectionis similar (MT) with a different woofer. The crossover was also designed by Dennis Murphy vs Rick Craig.

1) Is anyone here familiar with this design? If so, could you please provide feedback?
2) For a similar price, does a more modern driver ML TL 2- ways make sense, such as Paul's Brioso ML TL Using a Scan Speak 18W/8531G00 Woofer and a Transducer Lab N26CR2-A? (Albeit, I don't know if he is even sharing this design data)

I've pondered that design too. I have the upper 2/3 of the CanTilena, but like you, the woofers are just beyond my arbitrary audio toys budget. I had pieced together the mid & ribbon portion with the CanTilena crossover, sitting on a decent Usher woofer. It was just for fun - no measurements or sims. But the sound was amazing enough to keep hoping I might some day stumble over a big wad of cash to buy the Revelator woofers.

Wow, thank you for the quick responses. I've been reading this forum for a few years (but not posted due to signup issues) and just want to say thank you to the members here. Your knowledge and willingness to help and share on these boards have been really helpful for a complete novice like me.

I just purchased the Vianadi plans yesterday. Would also be curious if there are any previous builders willing to post some feedback. Trying to convince my brother to try them out.

My intent is to build a variation of the CanTiLena for myself using the Fostex F200A (which i already own) in place of the spendy SS woofers. The specs are surprisingly similar .

Also have the plans for the Bob Brines TL for the Fostex to use for the cabinet design. Thought it would be fun to set them up with the option to be run full range or as a 3 way (maybe even a 2 way with only the Fostex and ribbon tweeter).

I used the 4 ohm version of SS 22W in a giant 2.1 boombox. A very nice woofer.with higher sensitivity. But it needs a larger cabinet (1.8 to 2.0 ft3) for an F3 in the 30s. And it runs out of xmax approaching 50 W.

I agree with you on Usher woofers and I've used some myself. Comparing the SS Revelator woofer I used in the canTiLena to the SS Discovery woofer in the Vianadi, the Rev has an Xmax of 9 mm versus 5.8 mm for the Discovery and the Rev's Xlim is also larger than that of the Discovery. So, the Rev woofer will move more air without strain; however, unless one is trying to rattle the windows, and ignoring specific differences in distortion characteristics between the two woofers, I suspect there'd be little audible differences discernible to most people on most music. OTOH if one has the money, I wouldn't hesitate to recommend the Revelator.

Paul ,have you delved farther such as SS Illuminator or any of the AT woofs for any of your projects?

Comment

When I first designing the Brioso I had planned on using the SS 18W 4-ohm Illuminator along with a T-Labs Be tweeter, but switched to the 8-ohm Revelator and T-Labs ceramic tweeter to "save" ~$200 per cabinet, which ended up completely paying for the crossover components. I really don't think the Illuminator drivers are worth their higher prices and whatever benefits they might have I doubt I would be able to hear. I've never considered using AT drivers at all.
